AbstractAdmission control has been shown to be a preferred alternative to TCP-friendly congestion control for inelastic flows in heterogeneous networks shared by elastic and inelastic traffic [1]. However, it is possible for an inelastic flow to adopt different level of aggressiveness in implementing the admission control. How these different levels of aggressiveness affect the system performance remains an open issue. In this paper, we evaluate a full spectrum of (abstract) admission control algorithms in terms of their aggressiveness towards elastic flows. A totally aggressive version would admit an inelastic flow even if this means elastic flows' fair bandwidth share is reduced to close to zero. In the other extreme, a TCP-firiendly version would only admit an inelastic flow if its desired rate is no higher than what the elastic flows will receive after its arrival. We show that the performance of inelastic flows is asymptotically insensitive to their aggressiveness without strong assumptions about flow file size or holding time distributions. This makes a strong case for adopting a less aggressive, yet TCP-friendly admission control in a heterogeneous network. Extensive simulations are carried out to validate the performance, stability and asymptotic behavior the the proposed TCP-friendly admission control policy.
